Skype for Business gives no X.224 response to my request RRS feed

  • Question

  • hi, 

    I meet another issue with my C++ application, which is trying to get Lync client sharing content with SIP federation. The interesting part here is that one Lync Client ( Version: 15.0.4420.1017 MSO 15.0.4420.1017 64bits) works fine with my application. But another Lync Client( Version: Skype For Business 2015 15.0.4763.1001 MSO 15.0.4763.1003 32bits) does not work.

    The detailed info is that my application works as RDP client and Skype For Business as RDP Server; my application gets the TCP connection from Skype for Business and sends out the first X.224 Connection Request PDU according to MS-RDPBCGR. The Skype for Business does not give me any response until it's time out. 

    Network dump of the fist CR PDU.

  • Hello Green :

    We believe this query is duplicate of what you sent us yesterday at dochelp . As per discussion through dochelp, the reason of failure is bug in your code, which stands fixed now.

    Please let us know if our understanding is incorrect.

    Thanks
